Researchers at the Georgia Institute of Technology have developed a miniature generator that could power small electronics (such as cell phones and PDAs) and last up to 10 times longer than conventional batteries.
Such microgenerators, each the thickness of a dime, contain tiny spinning magnets that serve as their energy source -- a technology called a microelectromechanical system, or MEMS. The faster the magnets spin, the more energy they produce.
GIT hopes that its next generation of microgenerators will be powerful enough to power laptops, radios and GPS devices.
